This is really cute! I like how you did the colouring, wish I was that good with colour pencils ... A lot of red, which is a plus for me! I think the text in the background was a good addition, you are right. The foot is kind of squareish though, but that's a minor detail. You did good work on this drawing, thanks for sharing your talent.
Additonal comment: You might want to scan at a higher resolution first, and then resize it, rather than enlarging a small image and saving it. Or save the jpg in a higher resolution. Quality looks bad here.
